Schumacher was not impressed with Hamilton’s outing at Zandvoort and made his feelings clear during a recent appearance on the Backstage Boxengasse podcast.
“What I wanted to say is that Hamilton still has to be careful, because the speed wasn’t that bad, you could say,” said Schumacher.
“The race track wasn’t that challenging, but those mistakes at Zandvoort, two spins and then a penalty at the yellow flag before the start. I have to be honest, he needs to be a bit more professional.
“With his experience, that really shouldn’t happen to him and he really has to be careful with things like that so that the fans continue to support him, because that could also annoy the Tifosi. When everything goes right for Lewis Hamilton, he’s fast.
“But I’d say spinning twice at Zandvoort, then crashing his car into the wall and then that too, well, there was a bit too much going on that weekend, where you’d actually expect a bit more concentration from someone so experienced.”
Hamilton fared better at the Italian Grand Prix, coming home in sixth place with his penalty making it difficult to climb any higher up the finishing order.
It comes after Hamilton said it would be a while before he gets to break his podium drought, with the 40-year-old offering a bleak assessment of his future prospects.
“I think overall our performance [at the Italian Grand Prix] was fairly decent,” he said. “We obviously do not have the pace of the cars much further ahead.
“So, competing for the top three is off the cards for a while, but we keep pushing and trying to extract more. This weekend built a lot on my confidence with the car, [but] definitely I am still not 100 per cent comfortable in the car.”
